@Marvin how to setup jobTemplate using helm only? I can see that the worker created the work pool, but it's not using the jobTemplate configuration. The Helm jobTemplate configuration is NOT automatically used when the worker creates a work pool. The jobTemplate is only used if you manually configure it in the work pool's base job template. Looking at the Prefect documentation, the jobTemplate in the Helm chart should be used to override the default job template when the worker creates the work pool. However, this feature might not be working as expected, unless the work pool was created without this template.

Based on the research, I can explain how to properly set up the jobTemplate using Helm. You're correct that there's a specific process required to make this work. Here's how to properly configure the jobTemplate: 1. First, you'll need to create a work pool manually with the desired job template. You can do this in two ways:
Copy code
bash
# Option 1: Using the CLI
prefect work-pool create my-k8s-pool --type kubernetes

# Option 2: Using the UI
# Navigate to Work Pools → Create Work Pool → Kubernetes
2. After creating the work pool, you need to configure your
values.yaml
for the Helm chart with both the work pool name and the jobTemplate:
Copy code
yaml
worker:
  workPool: "my-k8s-pool"
  jobTemplate:
    spec:
      template:
        spec:
          containers:
            - name: prefect-job
              resources:
                requests:
                  memory: "512Mi"
                  cpu: "500m"
                limits:
                  memory: "1Gi"
                  cpu: "1000m"
          # Add any other Kubernetes pod spec configurations
          tolerations: []
          nodeSelector: {}
3. Apply the configuration:
Copy code
bash
helm upgrade --install prefect-worker prefecthq/prefect-worker -f values.yaml
Important notes: 1. The jobTemplate configuration in the Helm chart won't automatically update an existing work pool's base job template. You'll need to update the work pool's configuration separately through the UI or CLI. 2. To update the work pool's base job template, you can use:
Copy code
bash
prefect work-pool update my-k8s-pool --base-job-template /path/to/job-template.yaml
3. If you want to ensure the jobTemplate is used for all flows, you should: - Create the work pool first - Configure its base job template - Then deploy the worker using Helm The jobTemplate specified in your Helm chart's
values.yaml
will be used as a starting point for new job configurations, but it needs to be properly integrated with the work pool's configuration to take effect. For more detailed information about managing work pools and their configurations, you can refer to the Prefect documentation on managing work pools.
